Answer:
6
Step-by-step explanation:
you want to create two equations for each situation so if v=number of students that can fit in a van and c=number of students that can fit in a car then you can create the equations 3v+1c=22 and 2v+4c=28
then you want to make both equations equal to c
so for the first one you subtract both sides by 3v and you get c= -3v+22
and for the second one you subtract 2v from both sides and end up with 4c=-2v+28 and then divide both sides by 4 leaving you with c= -1/2v+7
then you make both of those equations equal to each other and solve for v
so -3v+22= -1/2v+7 and you end up with v=6
therefore, each van can hold 6 students

Patrick drives from P to Q at an average speed of 40 mph . His drive back from Q to P is at an average speed of 45 mph and takes two minutes less.
How far, in miles, is it from P to Q?
Answers
Answer:
Distance=12 miles
Step-by-step explanation:
d=distance
t=time going
d/t=40 mph going
t-2/60=time returning (2 minutes/60 minutes per hour)
d/(t-2/60)=45 mph returning
set up equations:
d=40t
d=45(t-2/60)
substitute:
40t=45(t-2/60)
40t=45t-90/60
40t=45t-3/2
0=5t-3/2
5t=3/2
t=0.3 hours or 18 minutes
(time returning=16 minutes)
substitute:
d=40t=40(0.3)
d=12 miles
P and Q are 12 miles far from each other.
Given that
Patrick drives from P to Q at an average speed of 40 mph
Also he drives from Q to P at an average speed of 45 mph
Let "s" be the distance between P and Q in miles.
Let "t" be the time in minutes
There are 60 minutes in 1 hours
[tex]\rm So \;in \; "t" \; minutes \; there\; will\; be = \dfrac{t}{60} \ hours[/tex]
By the definition pf average speed we can write that
[tex]\rm Average \; Speed = \dfrac{Total \; distance }{Total \; time}\\[/tex]
The speed is given in two situations in miles per hour
Case 1 When average speed = 40 mph
[tex]\rm 40 = \dfrac{s}{t/60} \\\\\rm {40 = \dfrac{60s}{t} .....(1) }[/tex]
Case 2 When average speed = 45 mph
Given that Patrick takes two minutes less
[tex]\rm 45 = \dfrac{s}{(t-2)/60} \\\\45 = \dfrac{60s}{t-2 } ....(2)[/tex]
Solving for "s" from equations (1) and (2) gives us
[tex]\rm \bold {s = 12}}[/tex]
So we can conclude that P and Q are 12 miles far from each other.

B There is a small chance that the event will occur.
C The event is likely to occur.
D The event will definitely occur.
Answers
B
Step-by-step explanation:
it would be a if the chance was 0.000 but it's 0.001 so there is a very very small chance of it happening
Answer:
Step-by-step explanation:
0.001 means 1/1000
The answer depends on what is being described.
If you are putting money into a lottery if you got odds of 1 in a 1000, you'd jump for joy at such good odds.
If you are putting money into the stock market and the chances of getting any kind of return is 1/1000, I think you'd start looking for something else to do.
That said, I think the answer you want is B, but I'm not fond of the question.
Find the measure of the exterior angle in the following triangle. DUE SOON PLZ HELP WITH STEP BY STEP
Answers
Answer:
The measure of an exterior angle = 125°
Hence, option A is correct.
Step-by-step explanation:
As the given triangle is a right-angled triangle ΔABC.
Given the angles
m∠A = 35°m∠C = 90°We know that the sum of angles in a triangle is 180°.
Thus,
m∠A + m∠B + m∠C = 180°
substituting m∠A = 35° and m∠C = 90° in the equation
35° + m∠B + 90° = 180°
125 + m∠B = 180°
subtract 125 from both sides
125 + m∠B - 125 = 180° - 125
m∠B = 55°
Thus, the measure of angle B is:
m∠B = 55°
As the exterior angle of the given triangle is adjacent to m∠B = 55°.
We know that the exterior angle of a triangle is equal to the sum of two opposite interior angles.
Here,
∠A and ∠C are two opposite interior angles of the exterior angle.
Thus,
The measure of an exterior angle is equal to the sum of two opposite interior angles.
as
m∠A = 35°m∠C = 90°so
Exterior angle = m∠A + m∠C
= 35° + 90°
= 125°
Thus, the measure of an exterior angle = 125°
Hence, option A is correct.

you can do it from another side too.
2a-20. 8 = a + 1. 2 ( opposite side of parallelogram are equal )
